Charging system and charging method for automobile power battery

The invention discloses a safety charging system and a charging method for an automobile power battery. The safety charging system for the automobile power battery comprises a power battery, a charger and a battery manager, wherein the power battery comprises a plurality of battery packs; each battery pack comprises at least one battery monomer; each battery pack and the charger construct a charging circuit; a switch is connected between each battery pack and the charger; and the battery manager is used for acquiring the voltage parameters and temperature parameters of each battery monomer in real time, processing these parameters, and controlling the switch-on/off of each switch according a processing result to charge a selected battery pack or stop charging, namely, charge the battery packs in sequence. Due to the adoption of the charging system and the charging method, the circuit current of system hardware can be lowered, the effects of balancing charging and reducing charging loss are achieved, and the safety is enhanced.
